ElasticSearch - doc_value in murmur3 hash - elasticsearch

Question

Continuing a previous question.
What am I trying to do?
Thanks to #AndreiStefan I'm trying to put a murmur3 hash off the heap, using doc_values:
"dynamic_templates": [
{
"murmur3_hashed": {
"mapping": {
"index": "not_analyzed",
"norms": {
"enabled": false
},
"fielddata": {
"format": "doc_values"
},
"doc_values": true,
"type": "string",
"fields": {
"hash": {
"index": "no",
"doc_values": true,
"type": "murmur3"
}
}
},
"match_mapping_type": "string",
"match": "my_prop"
}
}
]
I used stream2es for reindexing.
What is the result?
After a reindexing, the result property is:
"my_prop": {
"index": "not_analyzed",
"fielddata": {
"format": "doc_values"
},
"doc_values": true,
"type": "string",
"fields": {
"hash": {
"null_value": -1,
"precision_step": 2147483647,
"type": "murmur3"
}
}
},
What is the problem?
Why is the "index": "no", "doc_values": true missing in the result property?

This is the list of commands that I tested in ES 1.6.0:
PUT /test
{
"mappings": {
"_default_": {
"dynamic_templates": [
{
"murmur3_hashed": {
"mapping": {
"index": "not_analyzed",
"norms": {
"enabled": false
},
"fielddata": {
"format": "doc_values"
},
"doc_values": true,
"type": "string",
"fields": {
"hash": {
"index": "no",
"doc_values": true,
"type": "murmur3"
}
}
},
"match_mapping_type": "string",
"match": "my_prop"
}
}
]
}
}
}
POST /test/test_type/1
{
"my_prop": "xxx"
}
GET /test/test_type/_mapping
And I got this as output:
{
"test": {
"mappings": {
"test_type": {
"dynamic_templates": [
{
"murmur3_hashed": {
"mapping": {
"fielddata": {
"format": "doc_values"
},
"norms": {
"enabled": false
},
"index": "not_analyzed",
"type": "string",
"fields": {
"hash": {
"index": "no",
"type": "murmur3",
"doc_values": true
}
},
"doc_values": true
},
"match": "my_prop",
"match_mapping_type": "string"
}
}
],
"properties": {
"my_prop": {
"type": "string",
"index": "not_analyzed",
"doc_values": true,
"fielddata": {
"format": "doc_values"
},
"fields": {
"hash": {
"type": "murmur3",
"index": "no",
"doc_values": true,
"precision_step": 2147483647,
"null_value": -1
}
}
}
}
}
}
}
}
